SETUP DEFAULTS

 

Description: The SETUP DEFAULTS window contains various preprocessing utilities that are toggle switch activated. See the figure below.

 

Figure 9.4.12 Setup Defaults Menu

 

A detailed description of each option is given in the following section

 

-MENU POSTITION

 

Description: This function allows the user to change Menu position to left or right or right hand side of the display window, based on the user’s preference.

 

-ANALYSIS PROGRAM

 

Description: This option adjusts the property and material data to match the selected parameters of the solver.  The default solver code for DSI is DYNA.

 

 

The MATERIAL PROPERTY and ELEMENT PROPERTY menus change according to the analysis program.

 

Note: DSI is unable to convert existing properties into the selected solver format.

 

 

-AUTO SEGMENT END (toggle)

 

Description: This option allows the user to designate the end points of line segments to serve as control points.

 

Note: This function is used in conjunction with CONTROL POINT MESH.  DSI prompts the user to select control points on lines that are joined through the line segment option.

 

-CONTROL POINT MESH (toggle)

 

Description: This function pre-selects the points on a line for the desired node locations associated with the 2L, 3L, 4L, 6S, 8S, 9S, and 12S mesh programs.

 

-FLANGE MESH (toggle)

 

Description: This option turns on the ability of the automeshing routines to support a flange mesh option. The Flange Mesh option allows users to identify flange areas of spotwelded assemblies and requires that either 2 or 3 elements be placed on the width of the flange.

 

-CORNER BIAS MESH (toggle)

 

Description: This option allows the user to enter an element bias factor (0.625 to 1.6) relative to the selected corner of the line data that is to be modeled.  This function multiplies each adjacent element that is created from the selected corner by the bias factor.

 

Note: A bias factor greater than 1.0 generates proportionately larger elements from the selected corner. A bias factor less than 1.0 generates proportionately smaller elements from the selected corner.

 

Note: This function may be used with only the 2L, 3L, 4L, 6S, 8S, 9S, and 12S functions.

 

-EDGE BIAS MESH (toggle)

 

Description: This option allows the user to enter an element bias factor (0.625 to 1.6) relative to the selected edge of the line data that is to be modeled.  This function multiplies each adjacent element that is created from the selected edge by the bias factor.

 

Note: A bias factor greater than 1.0 generates proportionately larger elements from the selected edge.  A bias factor less than 1.0 generates proportionately smaller elements from the selected edge.

 

Note: This function may be used with only the 2L, 3L, 4L, 6S, 8S , 9S, and 12S functions.

 

-CHANGE COLOR MAP

 

Description: This function allows the user to change the default colors of the COLOR BAR for plotting of part color or contour color.

 

-ELEMENT SIZE

 

Description: This function allows the user to preset a default element size before generating the 2 LINE, 3 LINE, 4 LINE, or SURFACE mesh.

 

-SHADING OPTIONS

 

       Description: This function offers the following 3 options for shading a part or a model:

 

Options are:

GOURAUD SHADING (smooth shading)

FLAT SHADING NO EDGE

FLAT SHADING W/EDGE

 

Gouraud shading is the default setting for DSI. Flat Shading W/Edge displays the element outline in a shaded display.

 

 

-TRANSPARENCY FACTOR

 

Description: This function sets a degree of transparency for the shading option.  Factors closer to 0.0 (zero) increase opacity, while factors closer to 1.0 (one) decrease opacity.

 

-AUTOMATIC BACKUP (toggle)

 

Description: DSI will automatically create a backup database for the current DSI database. This parameter controls the frequency of this back-up process. The default for this parameter is OFF.

 

The back-up database is stored in the file named “*.*.bak”, where * is the name of the current database.

 

In the event of a software failure or database corruption, this file may be renamed or copied and then reopened in DSI.

 

-FILL HIDE METHOD

 

Description: DSI provides two methods of FILLHIDE (a hidden surface plot for all of the displayed elements): STENCIL BUFFER and POLYGON OFFSET. Various graphics cards may provide an improved display appearance by using either method. It is known that on SGI IRIX workstations, specifying the STENCIL BUFFER option may result in improved graphic display performance.

 

-ELEMENT TYPE DISPLAY

 

Description: The toggle switches in the ELEMENT TYPE DISPLAY determine what element types will be shown in the drawing window.  The default setting for all the switches is ON.

 

-TYPE IDENTIFIER

 

Description: This toggle switch controls the display of element type identifiers.  If the option is turned on, a symbol for the 1-D element types will be plotted at the center of the element to indicate the element type.  The identifier symbols for the various elements are listed in the following table:

The default for this option is off.
